Mozilla releases patch for Java Script Vulnerability
A bug discovered earlier this week in Firefox 3.5’s Just-in-time (JIT) JavaScript compiler was disclosed publicly by S.Berry on milw0rm. Just after three days worth of testing later, Mozilla has pushed out Firefox 3.5.1, with a fix for this error as well as corrections for several other bugs.
“ Firefox user zbyte reported a crash that we determined could result in an exploitable memory corruption problem. In certain cases after a return from a native function, such as escape(), the Just-in-Time (JIT) compiler could get into a corrupt state. This could be exploited by an attacker to run arbitrary code such as installing malware.”
The vulnerability was introduced in TraceMonkey, the JavaScript engine used in Firefox 3.5 that actually offers a decent speed boost to the browser. Oddly enough, TraceMonkey was already set to be patched this month by Mozilla, as bugs in the newest engine were listed in a July 1 meeting as the sole topcrash issue for Firefox 3.5. In other words, while vulnerabilities like this are horrible, this one came at a perfect time as developers were already giving TraceMonkey a thorough cleaning.

I strongly recommend that all firefox 3.5 users upgrade to this latest release. If you already have Firefox 3.5, you will receive an automated update notification within 24 to 48 hours. This update can also be applied manually by selecting “Check for Updates…” from the Help menu. You can download Firefox 3.5.1 from official Mozilla site.
